These results show that codA gene cloned from E. coli can express specifically in the anther of both monocotyledon and dicotyledon plant species upon induction of 5-FC, and the in vivo expression product of the gene can transform the 5-FC used externally into 5-FU, which leads to all or partial inactivity of anthers and/or pollens.

以上结果表明，codA基因在单子叶植物和双子叶植物花药中的特异性表达，能将外用的5-FC在体内转化为5-FU，导致花药或花粉的部分和全部失活。

In dicotyledonous and nongraminaceous plants, NAS synthesizes nicotianamine which is responsible for iron storage and transportation, and the expression of NAS gene is not induced by iron deficiency.

在双子叶和非禾本科单子叶植物中，烟酰胺的主要功能是铁离子的储藏和运输，NAS基因的表达不受缺铁胁迫诱导。

Other leaf samples were collected from monocotylous and dicotyledonous plants, respectively to test this procedure. A series of PCR reactions were tested, which proved this method was widely acceptable.

以有代表性的单子叶和双子叶植物叶片为材料，经过多种内源基因PCR反应的反复验证，证实了这种方法的广泛适用性。

A clearly defined endodermis is seen in all roots and in the stems of the non seed-bearing vascular plants and some dicotyledons.

所有不产生种子的维管植物和一些双子叶植物的茎中都可以清楚的显示出这一结构。

The plantlets of soybean, cucumber and garden balsam were inoculated by wild-type Agrobacterium rhizogenes K599, and hairy root was induced on inoculated sites in vivo. The frequencies of hairy root induction from wound cotyledons of soybean, cucumber and garden balsam were 100%, 65% and 91%, respectively.

利用野生型的发根农杆菌K599对属于不同科属的大豆、黄瓜和凤仙花进行活体感染实验，结果表明，发根农杆菌K599可使切割后的大豆、黄瓜和凤仙花子叶形成不定根，生根频率分别为100%、65%和91%。

Its hypocotyl and leaf of cotyledon were better explants for inducing calli on the MS medium with 0.1mg/L NAA .

幼苗的下胚轴和子叶叶片在MS+0.1mg／L NAA的培养基上可以获得较好的愈伤组织。

Therefore,this is the first receptor-like resistance geneisolated from wheat,a monocotyledon crop.TaLRR1 encode a membrane anchoringglycoprotein that can be divided into seven domains.

这是首次从小麦中克隆到的与双子叶植物番茄的Cf-2和Cf-4有类似结构的细胞外受体类抗病候选基因。

Eustele The STELE arrangement found in most gymnosperms and dicotyledons in which the vascular tissue is arranged into a ring of discrete bundles separated by medullary rays, all contained within a single ring of endodermis and pericycle.

真中柱：发现于大多数裸子植物和双子叶植物的中柱类型，其维管组织由不连续的，被髓射线分开维管束排列成环状。所有的微观组织都包含在内皮层和中柱鞘以内。

Seeds ellipsoid to pyriform, dull to ± shiny; seed coat with thick inner layer of dense black sclerenchyma surrounded by outer layer of compact parenchymatous tissue; endosperm copious; embryo straight or nearly so; cotyledons ovate to elliptic, flattened; hypocotyl superior.

种子椭圆形到梨形，黯淡到发亮；种皮具厚的紧密黑色的厚壁组织内层，被紧密的薄壁组织外层所包裹；胚乳丰富；胚直立或近直立；子叶卵形到椭圆形，扁平；下胚轴上位。

Histochemical analysis showed that the specific expression of GUS in seeds was not restricted to the endosperm cells, but also occurred in the vascular bundle and epithelial cells of scutellum.

组织化学分析发现在水稻种子专一性表现的GUS活性并不局限於胚乳细胞，维管束组织及子叶盘的上皮细胞也有明显的表现。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
